Install the device in an area that ensures the correct degree of protection, and take all due care when drilling holes in the box for the cable glands and/or hoses. 2. Avoid using multi-pole cables with conductors connected to inductive and power conductors and signal conductors like sensors and digital inputs. 3. Avoid inserting ducts and power cables with signal cables (sensors and digital inputs) in these. 4. Minimize the length of the connecting cables to prevent these from coiling up and adversely affecting the electronics through induction. 5. All the conductors of the cables must be of an appropriate size to withstand the required load. 6. When extensions are needed for the sensors, it is necessary to use conductors of a suitable size measuring no less than 1 mm². Extension or shortening of the sensors may alter the factory settings; use an external thermometer, therefore, for testing and calibration. STANDARD EQUIPMENT FOR ASSEMBLY AND USE 2.2 The PEV PULSE electronic controller is provided with the following for assembly and use: • 1 x user manual. Rev. 01-14 USER AND MAINTENANCE MANUAL Page 5 PEV PULSEContents 2.3 CHAP. 2 - Installation INSTALLATION OF BOARD Fig. 1: Install the module on the DIN guide and close the bottom clamp to hold it in place. Make all the electrical connections with reference to the diagrams of the relative model (see the relative tables in the ANNEXES). During the cabling process, it is advisable to keep the power conductors isolated from the signal conductors.

Below the LSH threshold, the ELS protection forces the PID control to close the valve more quickly and bring the value back up to the superheat setpoint. Low superheat protection When this is enabled and SH < LSH, the PID integration timer is set on the basis of the selection of 1 to 7 of the ELS. Value 1 is for the quickest closing time. Enabling of this protection starts the SHd counter for activating the LSH alarm. THE LSH PROTECTION TAKES PRIORITY OVER THE LOP PROTECTION. THE LSH PROTECTION IS NOT ACTIVATED DURING THE START-UP PHASE (ESt TIMER) OR DURING THE DEFROSTING OR POST-DEFROSTING PHASE (Edt TIMER) SHd MOP EMO MOd LOP Activation delay of the superheat alarm: the LSH superheat alarm is triggered only after it has remained active for the SHd time.
